History

Historical Context

On June 19 1961 the U.S. Supreme Court issued Mapp v. Ohio, a 6-3 ruling that incorporated the Fourth Amendment’s exclusionary rule against the states. The decision built on Weeks (1924) and Wolf (1949) and required police, including the FBI, to obtain warrants before using seized evidence. Judge Carro’s denial of Mangione’s diary-suppression request applies that same rule to the 2026 trial.
